Substitute Part Grouping Explanation

Substitution eligibility for the AP130-20YG-13 is determined by the following critical parameters:

Output Voltage (Fixed): 2V
Output Current Capability: 300mA
Input Voltage (Max): 5.5V
Package / Case: TO-243AA
Supplier Device Package: SOT-89-3 or SOT-89R-3
Output Configuration: Positive
Output Type: Fixed
Number of Regulators: 1
Protection Features: Over Current, Over Temperature, Short Circuit
Operating Temperature Range: -40°C ~ 85°C (TA)
RoHS Status: ROHS3 Compliant
Product Status: Active

The AP130-20YRL-13 qualifies as a parametric equivalent because it maintains identical electrical specifications for output voltage, output current, input voltage maximum, operating temperature range, protection features, and compliance certifications. The primary distinction is the supplier device package variant (SOT-89R-3 versus SOT-89-3) and a marginally lower dropout voltage specification (0.4V versus 0.5V at 300mA), which represents an improvement in performance characteristics.

Engineering Selection Recommendations

Both the AP130-20YG-13 and AP130-20YRL-13 are active products from Diodes Incorporated with full ROHS3 compliance and identical electrical performance specifications. Selection between these parts should be based on:

Package Variant Availability: The AP130-20YG-13 uses SOT-89-3 packaging, while the AP130-20YRL-13 uses SOT-89R-3 packaging. Both are housed in the TO-243AA case. Verify PCB layout compatibility with the specific package variant required for your application.
Dropout Voltage Performance: The AP130-20YRL-13 offers a 0.1V lower maximum dropout voltage (0.4V versus 0.5V at 300mA), which may provide marginal efficiency benefits in power-constrained applications.
Inventory and Lead Time: Current inventory levels differ between variants. The AP130-20YG-13 has 15,100 units in stock, while the AP130-20YRL-13 has 5,939 units available. Supply chain considerations may influence part selection.
Compliance and Certification: Both parts maintain identical compliance status (ROHS3 Compliant, REACH Unaffected, EAR99 classification). No additional qualification is required when substituting between these variants.

Frequently Asked Questions (FAQ)

Q: Can the AP130-20YRL-13 directly replace the AP130-20YG-13 in an existing design?

A: Yes, the AP130-20YRL-13 is a direct parametric equivalent. Both parts deliver identical output voltage (2V), output current (300mA), input voltage rating (5.5V maximum), and operating temperature range (-40°C to 85°C). The primary consideration is package variant compatibility. Verify that your PCB layout accommodates the SOT-89R-3 package if substituting the AP130-20YRL-13 for the SOT-89-3 variant.

Q: What is the difference between SOT-89-3 and SOT-89R-3 packages?

A: Both packages are housed in the TO-243AA case and are mechanically compatible. The SOT-89R-3 designation indicates a tape and reel variant with potential manufacturing or lead configuration differences. Consult the respective datasheets to confirm pin compatibility and PCB footprint alignment for your specific application.

Q: Are there any electrical performance differences between these parts?

A: The AP130-20YRL-13 specifies a maximum dropout voltage of 0.4V at 300mA, compared to 0.5V for the AP130-20YG-13. This represents a 0.1V improvement and may provide marginal efficiency gains in applications operating near the minimum input voltage threshold. All other electrical parameters, including quiescent current, PSRR, and protection features, are identical.

Q: Do both parts require the same PCB layout and external component values?

A: Yes. Both the AP130-20YG-13 and AP130-20YRL-13 are pin-compatible and functionally equivalent. External component requirements (input/output capacitors, bypass networks) remain unchanged. Verify package footprint compatibility before layout finalization.

Q: Are both parts compliant with current environmental and trade regulations?

A: Yes. Both the AP130-20YG-13 and AP130-20YRL-13 are ROHS3 Compliant, REACH Unaffected, and classified as EAR99 for export control purposes. No additional compliance documentation is required when substituting between these variants.
